Announcements • HW3 is online, due Thursday night March 30 • No class Wednesday, no section Friday – enjoy the break

Last week… • We wrapped up last week talking about remedies for breach • Money damages: expectation damages, reliance damages, opportunity cost damages • Specific Performance • Peeveyhouse v Garland Coal – P’s wanted specific performance, G got away with paying very small damages • Today, I want to review what we know about incentives caused by remedy

Effects of different remedies on… decision to perform or breach decision to sign or not sign investment in performing investment in reliance

Plane worth $500,000 to youPrice $350,000Cost: either $250,000 or $1,000,000 Remedies and breach Expectation Damages Specific Performance Costs Low – Perform Costs High – Perform Costs High – Breach Costs Low – Perform Costs High – Perform CostsHigh – Renegotiate I get 100,000 -650,000 -150,000 I get 100,000 -650,000 -400,000 –650,000 + ½ (500,000) You get 150,000 150,000 150,000 You get 150,000 150,000 400,000 150,000 + ½ (500,000) Total 250,000 -500,000 0 Total 250,000 -500,000 0 • Transaction costs low  either leads to efficient breach, but seller prefers “weaker” remedy • Transaction costs high  S.P. leads to ineff. performance

Remedies and breach • Opportunity cost damages, or reliance damages • Inefficient breach when transaction costs are high • Renegotiate contract to get efficient performance when transaction costs are low • Like nuisance law: any remedy leads to efficient breach with low TC • But only expectation damages do when TC are high • Unfortunate contingency and fortunate contingency

Efficient signing • Specific Performance • If costs stay low, I get $350,000 – $250,000 = $100,000 profit • If costs rise, I take $400,000 loss • Am I willing to sign this contract? • Even expectation damages face this problem • Expectation damages: costs stay low, same $100,000 profit • Costs rise, $150,000 loss • If probability of high costs is ½, I won’t sign contract • Expectation damages lead to efficient breach, but may not lead to efficient signing

Reliance – did example a while ago • If reliance investments increase the damages you receive, we expect to get overreliance • To get efficient reliance, need to exclude gains from reliance in calculation of expectation damages • But then promisor’s liability < promisee’s benefit, leading to inefficient breach • With low transaction costs, fix this through renegotiation • But what about unobservable actions the promisor needs to take, to make breach less likely? • Investment in performance Skip

Investment in performance • Investments promisor can make to reduce likelihood that he/she will have to breach • We said expectation damages lead to efficient investment in performance. Why? • Social cost = private cost = actual cost of investment • Social benefit = (reduction in prob of breach) x (social cost of breach) = (reductionin prob of breach) x (promisee’sbenefit from performance) • Private benefit = (reduction in prob of breach) x (private cost of breach) = (reduction in prob of breach) x (promisor’s liability) • So if liability = anticipated benefit, SC = PC, SB = PB  efficient behavior • If liability < anticipated benefit, PB < SB  less than efficient investment • If liability > anticipated benefit, PB > SB  more than efficient investment

Investment in performance(continuing with airplane example) • Suppose probability of breach if I invest nothing is ½… but for every $27,726 I invest, I cut the probability in half • Invest nothing  probability of breach is 1/2 • Invest $27,726  probability is 1/4 • Invest $55,452  probability is 1/8 • Any investment z  probability is .5 * (.5) z / 27,726 • Wrote it this way so p = .5 e – z / 40,000

Investment in performance(continuing with airplane example) • Suppose you’ve built a $90,000 hangar • Increases value of performance by $180,000… • …so value of performance is $150,000 + $180,000 = $330,000 • Probability of breach = .5 e – z/40,000 • Let D = damages I owe if I breach • Same questions as before: • What is efficient level of investment in performance? • How much will I choose to invest in performance?

Investment in performance(continuing with airplane example) • Suppose you’ve built a $90,000 hangar • Increases value of performance by $180,000… • …so value of performance is $150,000 + $180,000 = $330,000 • Probability of breach = .5 e – z/40,000 • Let D = damages I owe if I breach • Same questions as before: • What is efficient level of investment in performance? Enough to reduce probability of breach to 40,000/430,000 • How much will I choose to invest in performance? Enough to reduce probability of breach to 40,000/(100,000 + D)

What do these results mean? • What is the efficient level of investment in performance? • Enough so that p(z) = 40,000/430,000 • What will promisor do under various rules for damages? • Enough so that p(z) = 40,000/(100,000 + D) • So if D = 330,000, efficient investment in performance • D = 330,000 is promisee’s benefit, including reliance • So expectation damages, with benefit of reliance, leads to efficient investment in performance • If D < 330,000, too little investment in performance • If D > 330,000, too much • Makes sense – think about externalities

Effects of different remedies on… decision to perform or breach decision to sign or not sign investment in performing investment in reliance

Paradox of compensation Expectation damages include benefit from reliance investments Expectation damages exclude benefit from reliance investments • Efficient breach • Efficient investment in performance • Over-reliance • Inefficient breach • Underinvestment in performance • Efficient reliance • Is there a way to get efficient behavior by both parties? Skip

We already saw one possible solution • Have expectation damages include benefit from reliance… • …but only up to the efficient level of reliance, not beyond • That is, have damages reward efficient reliance investments, but not overreliance • Promisee has no incentive to over-rely  efficient reliance • Promisor still bears full cost of breach  efficient performance • Problem: this requires court to calculate efficient level of reliance after the fact

Another clever (but unrealistic) solution • The problem: • Damages promisor pays should include gain from reliance if we want to get efficient performance • Damages promisee receives should exclude gain from reliance if we want to get efficient reliance • Solution: make damages promisor pays different from damages promisee receives! • How do we do this? Need a third party

“Anti-insurance” • You (promisee) and I (promisor) offer Bob this deal: • If you rely and I breach, • I pay Bob value of promise with reliance (airplane plus hangar) • Bob pays you value of promise without reliance (airplane alone) • Bob keeps the difference • You receive damages without benefit from reliance; I pay damages with benefit from reliance

“Anti-insurance” • You (promisee) and I (promisor) offer Bob this deal: • If you rely and I breach, • I pay Bob value of promise with reliance (airplane plus hangar) • Bob pays you value of promise without reliance (airplane alone) • Bob keeps the difference • You receive damages without benefit from reliance;I pay damages with benefit from reliance • Offer the deal to two people, make them pay up front for it

Reminder: what do courts actually do? • Foreseeable reliance • Include benefits reliance that promisor could have reasonably anticipated

Repeatedinteractions

Repeated games

Repeated games Player 1 (you) Trust me Don’t Player 2 (me) (100, 0) Share profits Keep all the money (150, 50) (0, 200) • Suppose we’ll play the game over and over • After each game, 10% chance relationship ends, 90% chance we play at least once more…

Repeated games • Suppose you’ve chosen to trust me • Keep all the money: I get $200 today, nothing ever again • Share profits: I get $50 today, $50 tomorrow, $50 day after… • Value of relationship = • Since this is more than $200, we can get cooperation

Repeated games and reputation • Diamond dealers in New York (Friedman) “…people routinely exchange large sums of money for envelopes containing lots of little stones without first inspecting, weighing, and testing each one” “Parties to a contract agree in advance to arbitration;if… one of them refuses to accept the arbitrator’s verdict, he is no longer a diamond merchant – because everyone in the industry now knows he cannot be trusted.”

Repeated games and reputation • The first purpose of contract law is to enable cooperation, by converting games with noncooperative solutions into games with cooperative solutions • The sixth purpose of contract law is to foster enduring relationships, which solve the problem of cooperation with less reliance on courts to enforce contracts • Law assigns legal duties to certain long-term relationships • Bank has fiduciary duty to depositors • McDonalds franchisee has certain duties to franchisor

Repeated games and the endgame problem • Suppose we’ll play agency game 60 times • $50 x 60 = $3,000 > $200, so cooperation seems like no problem • But… • In game #60, reputation has no value to me • Last time we’re going to interact • So I have no reason not to keep all the money • So you have no reason to trust me • But if we weren’t going to cooperate in game #60, then in game #59…

Repeated games and the endgame problem • Endgame problem: once there’s a definite end to our relationship, no reason to trust each other • Example: collapse of communism in late 1980s • Communism believed to be much less efficient than capitalism • But fall of communism led to decrease in growth • Under communism, lots of production relied on gray market • Transactions weren’t protected by law, so they relied on long-term relationships • Fall of communism upset these relationships

One other bitI like from Friedman

Friedman on premarital sex

That’s it for contract law • Purposes for contract law: • Encourage cooperation • Encourage efficient disclosure of information • Secure optimal commitment to performance • Secure efficient reliance • Provide efficient default rules and regulations • Foster enduring relationships • After break, we’ll begin Tort Law
